This invention relates to stove construcmanner of forming my novelenameledmantion and particularly to a manifold'for supifold 2, and the manner, of assembling the i plying the fuel to the various burner strucsame, Fig. 5 showing the plain sheet;metal tures, and method of forming same. i 7 stock, Fig. 6 illustrating the, manner of 5 In gas and vapor stoves and other similar punching the same, Fig. 7 showing the man- 60 structures the present tendency is toward ner of rolling the same to form the tube, and enameled stoves and designs which make for Fig. 8 the manner of assembling the enamcleanliness. andsanitariness, and which in eled tube over the. rough caster Wrought general, results in a very pleasing article iron or steel pipe. i v

Such enameled surfaces In Fig. 1 of the drawings I have shown my 65 in addition to being sanitary may be very novel porcelain enamel-ed, manifold as it apeasily cleaned by merely wiping with a wet pears with respectto the stove structure, and cloth. Many attempts have been made to it will be noted that this manifold is:one of enamel the manifold struct ,re so as'to match. the most prominent parts of the stove and it v up and synchronize with the other enamwill be obvious that when the same is porce- 70 eled parts of the stove, as a stove with a lain enameled with the same smooth, even porcelain enameled manifold presents; a finish as the other porcelain enameled parts. much more pleasing effect with a I stove of the stove that it will present what may be which is porcelain enameled with anickeled termed a very beautiful stove structure,

manifold. Howeventhese attempts to seandwill materiallyassist in taking the stove 75 cure a porcelain enameled manifold have out of the class of an ordinary cooking im been unsatisfactory, mainly for the reason plementand make it an article of beauty. that the porcelain enameling of a wrought In. providing a porcelain enamcled maniiron, steel or cast iron manifold ismechanif ld t t I d n t tt t t i any cally impractical and the resulting product, way porcelain enamel the surface .of the 8 if attempted, is generally full of blisters and manifold pipe itself, whether of wrought is generally unsightly in appearance, iron, cast iron or teel, butthis pipe is left It is the object of the present invontiOn to in its rough unfinished state" as received provide a porcelain enameled manifold from the manufacturer. structure which completely harmonizes with I t ad of utilizing the r gh manifold 85 the porcelain enameled parts of the stove pipe itself I preferably take a strip of sheet structure, and the enameled surface of which steel, which may be of 22 gage Armco iron, is smooth and even to correspond with the or any suitable sheet metal stock may be used porcelain enameled surfaces of the stoveas desired. This stock is flat, as shown in In he drawing 7 i Fig. 5 and may be designated 1, and is pref- 9o Fig. l is a fragmentary perspective view erably of a width so that after being rolled of a stove embodying my novel manifold up it will be of a diameter so as to easily slip Before rollstructure, also illustrating the prominence over the rough manifold rope. of the manifold at the front of the stove. ing up the piece of stock 1, I preferably Fig. 2 is. a detail view of the manifold fabricate the .same by punching out suitable structure itself showing the enameled maniholes 2, whichare spaced to correspond to fold shell broken away. the spacing of the valves 3 which lead from Fig. 3 is a sectional view taken on line the rough manifold pipe. The piece ofstoclr 3-3 of Fig. 2 and illustrating the posi- 1 may then be rolled up by any suitable 7 t-ioning of the auxiliary conduits, or valves, means so as to present a tube, as shown in whereby to hold the enameled shell in place Fig. 7, which has an inside diameter slightrelatively to the rough conduit. 1y greater than the outside diameter of the Fig. 41-. is a fragmentary longitudinal secrough manifold pipe and which is provided tional view of one end of the manifold strucwith suitable apertures 2 to' register with I 50 ture illustrating particularly the recessed the valve structures. Theseams of this tube cap fitting and the manner of positioning may be joined in any manner desired.

the enameled manifold within the recessed After the tube has been fabricated it may be porcelain enameled 1n the same manner portion of the cap. I

Figs. 5 to 8 are progressively arranged as the various other sheet Inetalplates going views, partly diagrammatic, illustrating the to make up the general stove structure". The .9

shell or tube being of sheet metal it'will be just as easily porcelained as the other pieces of sheet metal stock and will take a smooth, even porcelain finish which will match perfectly with the porcelain finish on the other parts of the stove.

This porcelain enameled tube may then be slipped over the rough manifold conduit un til the apertures 2 match with the tapped J sist of an elbow 4 and a cap 5. I The cap and elbow are preferablyrecess'ed, as at 6, so as to nicely'fit over the ends of .the porce lain enameled tube, as cle'arly shown in Fig. 4. The elbow and cap are preferably standarcl nickel'ed fittings.

I't Will'therefore beseenthat I have provided a new'article of manufacture, namely, a porcelain enameled manifold, the enamel finish of which is smooth and uniform correspending exactly with the enamel finish of the other parts of the stove. It will further be obvious that this porcelain enameled manifold is a very simple and cheap construction and completely does away with the necessity ofnickeling the rough manifold conduit. The structure is very easily asseni' bled an d p re sents an easily cleanable sur face, the only nickel parts being the special cap and. elbow fittings which are readily accessible for cleaning and Which-are also'positioned out of the way so as not to be subject to the necessity of as frequent cleaning as conduit for supplying fuel to burners, auxiliary conduits leading away from said main conduit, an enameled shell fitting around said main conduit and provided with suitable apertures registering with said atl'xil iary conduits.

2. A manifold structure for stoves of the type having enameled surfaces, comprising-a main conduit for supplying fuel-to th 'burners, auxiliary conduits. leading away from said-main conduit, special fittings .at-e'afch end of-said main conduit, and an enameled shell, cores aonding in appearance to the" enameled surfaces of the stove, fitting around said main conduit and provided with suitable apertures registeringwith said'a'uxiliary conduits, the ends of said enameled she'll beingpo'siticned within said special fittings.

3. A manifold structure for stoves of the typ e having enameled surfaces, comprising a relatively rough main conduit'for supplying fuel to the burners, auxiliary conduits leading away from said main conduit, and'a'n enameled sheet metal shell, corresponding in appearance to the enameled surfaces of the stove and fitting around said'main conduit.

In testimony whereof I affi'X' my signature.
